In the present paper, we investigate the feasibility of wave electricity production in Italian seas by the deployment of the Seabased wave energy converter (WEC). A numerical model of the coupled buoy-generator system is presented, which simulates the behavior of the wave energy converter under regular waves of different wave heights and periods. The hydrodynamic forces, including excitation fo...

Abstract: Empirically based modeling is an essential aspect of design for a wave energy converter. Empirically based models are used in structural, mechanical and control design processes, as well as for performance prediction. Both the design of experiments and methods used in system identification have a strong impact on the quality of the resulting model. This study considers the system iden...

with the prolonged use of domestic centrifugal pump, due to erosion, corrosion and an unbalance the sever vibration of the pump are resulted. an erratic sound coming out of pump makes the user uncomfortable. here, tuned vibration absorber (tva) is used as a vibration controlling device. it is designed to reduce the rms velocity below 20% of the circumferential speed, at which the impeller is ba...

To increase the amount of energy captured from a vibrating buoy in ocean with simple mechanism, this paper proposes two-body point absorber wave converter (WEC) tuned inerter. The inerter mechanism consists spring, linear damping element, and component called This was originally proposed field civil engineering as structural control device which can absorb structures effectively by taking advan...

The present work addresses the need for an efficient, versatile, accurate and open-source numerical tool to be used during design stage of wave energy converters (WECs). device considered here is heaving point-absorber developed tested by Sandia National Laboratories. smoothed particle hydrodynamics (SPH) method, as implemented in DualSPHysics, proposed since its meshless approach presents some...

INTRODUCTION Of interest, in this study, is the quantification of uncertainty in the performance of a two-body wave point absorber (Reference Model 3 or RM3), which serves as a wave energy converter (WEC). We demonstrate how simulation tools may be used to establish short-term relationships between any performance parameter of the WEC device and wave height in individual sea states. We demonstr...

The use of renewable energy sources is one of the most relevant goals to be achieved in order to match the climate protection targets. As a case study, the paper shows the current electrical energy production by sources in the Sicilian context. Among the renewable energy sources, the paper investigates the wave energy potential along the Sicilian coasts, because of the favorable climate around ...
